Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is part-structure detail view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, 2, it comprises that mainly one is installed in frame 2 on the platform 1, one and cantilever 3 described frame 2 upper end hinges and can 360 degree rotations and one and the swing arm 4 of described cantilever 3 hinges; One fixture 5 with slide rail 6 is installed in the described swing arm 4; The upper end hinge of described fixture 5 has a rocking bar 7, and the lower end is connected by the slide block 8 that the slide rail 6 and on it is fixedly mounted on the motor cabinet 9, and this slide block 8 passes through connecting rod one 10 mutual hinges with described rocking bar 7; One motor 11 is installed on the described motor cabinet 9, a cam 12 is installed in the rotating shaft of this motor 11; Described cam 12 links to each other with a drive link 14 with grinding head 15 by connecting rod 2 13; Described drive link 14 vertically passes the fairlead 16 that is fixed on the motor cabinet 9; One handle 19 that is provided with on ﹠ off switch 17 also is installed on the described motor cabinet 9; Described on ﹠ off switch 17 is electrically connected by power line 18 and external power source with described motor 11, and wherein motor 11 is connected with on ﹠ off switch 17, after the plug of power line 18 and external power source are electrically connected, by the folding of on ﹠ off switch 17, controls the running of motor 11.

Described frame 2 bottoms are provided with threaded perforate 20, and are fixedly mounted on a side on platform 1 surface by double-screw bolt 21.

Be provided with a support 22 for place work piece on the described platform 1; One fixation kit for fixation workpiece also is installed on the platform 1 of described support 22 inboards; Described fixation kit comprises that one is fixed on the threaded column 23 of surface band on the platform 1; Be threaded connection a pressing plate 24 on the described column 23.

One protective cover 25 also is installed on the described motor cabinet 9; Described protective cover 25 is enclosed in described cam 12, connecting rod 2 13 and drive link 14 wherein, and grinding head 15 is arranged on protective cover 25 outsides, Figure 2 shows that the detail view of removing behind the protective cover.
